Hello! My wife and I moved into a home last fall with an 18x36 in-ground pool. It has an Pentair WhisperFlo pump. The company that opened the pool last month mentioned that I should consider a more energy efficient unit. They didn't try to hard sell me on a particular system, but I would like to stay with Pentair. If I wanted to upgrade, which should I look at? The current pump is 1 HP / 60hz.
Also, is this something I could install OR is it something that should be installed by a professional? Just curious.
